I'm running SSH Communications version of SSH (ssh-3.1.2) and am trying
to login to a Solaris 9 machine running Sun's version of SSH. However,
I'm getting the following error:
warning: Authentication failed.
Disconnected; key exchange or algorithm negotiation failed (Key
exchange failed.).
More verbose output shows the following:

Anyone else experiencing this? I have tried using a different MAC as
well as using a different encryption algorithm and nothing seems to
work. I would appreciate any information anyone has on this.
